Hi everyone, i have this project to make an up/ down counter with 74LS192 and 74LS47 and 7 Segment.
when i build the circuit on a project board the reset and down counter works fine, but the up button not working.
The circuit i build as shown bellow.
I've also read this thread:
https://forum.allaboutcircuits.com/threads/74192-up-down-counter-problems.40101/
and tried to grounded the input from 74LS192, on the simulation all the button works fine but on real circuit the problem occur.
is there anything i can do to fix this?
Thanks in advance
